I’m pretty sure it 9 13/20
Answer:
Color : ___Green __yellow ___purple __ Grey
Prob : ____0.30 ___0.10 ______ 0.35 ___ 0.25
4 pins
Step-by-step explanation:
Color : ___Green __yellow ___purple __ Grey
Prob : ___. _______________ 0.35 ___ 0.25
P(green) = 3 * P(yellow)
ΣP = 1
Let
P(yellow) = x
P(green) = 3x
Hence,
x + 3x + 0.35 + 0.25 = 1
4x + 0.60 = 1
4x = 1 - 0.60
4x = 0.40
x = 0.4 / 4
x = 0.1
Hence,
P(yellow) = 0.1
P(green) = 0.1 * 3 = 0.3
Color : ___Green __yellow ___purple __ Grey
Prob : ____0.30 ___0.10 ______ 0.35 ___ 0.25
B)
If there are 14 pins in bag :
Number of green pins :
X * p(x)
14 * 0.3
= 4.2
= 4 pins
Answer:
36
Step-by-step explanation:
"Two more" = + 2
"quotient of a number and 6" = n/6
"equal to 8" = = 8
Set the equation:
n/6 + 2 = 8
Isolate the variable n. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 2 from both sides.
n/6 + 2 (-2) = 8 (-2)
n/6 = 8 - 2
n/6 = 6
Isolate the variable n. Multiply 6 to both sides.
(n/6)(6) = (6)(6)
n = 6 * 6
n = 36
36 is your answer.
~
-3x-2(5x-7)=-12
-3x-10x+14=-12
-12-14=-26
-3x-10x= -13x
So -13x=-26
x= 2
Walter is right cause 30x5 equals 150
